Please explain the procedure for
Stc injector type engine
Topstop injector type engine  

Answer
       On Topstop injector engine
The injector adjustment is Zero-Lash,There is a special "T" handle torque wrench (5-6 inlbs)to set injectors.The valves adjust int 0.011 & ex 0.023.
   Mark           Valve             INJ
   A               1                 5
   B               5                 3
   C               3                 6
   A               6                 2
   B               2                 4
   C               4                 1

On the STC,you adjust valves & inj on same cyl.The mark A is now 1-6,B is 2-5, & C is 3-4.Valves are Int 0.014 & Exhaust is 0.027.The injector you torque (60 inlbs) to bottom injector plunger out,then tighten the jam nut down.Adjust the Injector first,then the valves.
